RAYPROOF BUI LDING BLOCK Filed March 20, 1929 ATTORNEY Patented Oct. 28, 1930 UNITED STATES PATENT OFFICE DAVID E. BARRY, OF BROOKLYN, NEW YORK RAYPROOF BUILDING BLOCK Application filed March 20, 1929. Serial No. 348,507.

pitals, doctors and dentists oflices and other placeswhere X-ray and other like machines are used, the rays from which are capable of enetrating ordinary wall structures not protected thereagainst.

Another object of the invention resides in a ray-proof block made of cement, Cinders or the like in which a layer of ray-proof material is embedded therein with its edges extending beyond the several faces of the block to permit the projecting ends or flanges to overla the ends or flanges of the next adjacent blocks, whereby the joints between the blocks are sealed against the penetration of rays therethrough.

A further object is to provide a ray-proof block in which a lead plate is embedded cen trally therein with end portions projecting therebeyond, and which ends may be bent angularly so that overlapping of the ends of the adjacent blocks in a wall structure will not interfere with the perfect alignment of the blocks when placed end to end, and one above the other.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described,are particularly pointed out in the appended claims, and are illustrated in the accompanying drawin in which a Figure 1 is a perspective view of one of my improved ray-proof blocks.

igure 2 is a horizontal sectional view through a wall structure constructed of my rayproof blocks.

Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 1.

Figure 4 is a perspective view of the rayproof plate per se.

Figure 5 is a sectional perspective view of a slight modified form of ray-proof plate.

Referring to the drawing, the reference numeral 10 designates my improved rayproof block in its entirety which includes a l wall is non-pierce body 11 of rectangular shape and which may be constructed of cement, cinders, or the like, through which X-rays and other similar rays may ordinarily penetrate. However, I make this body ray-proof by embedding a. layer of bendable ray-proof material or plate 12 centrally therein and which is preferably lead, as it is well-known that lead acts as a barrier against the penetration of such rays. The plate 12 in thisinstance is of such size that its ends project beyond the end faces of the body into flanges 13 while the longitudinal side of the plate extend beyond the adj acen-t longitudinal flat faces of the body to provide flanges 14.

To securely anchor the plate 12 to the body 11, I provide transverse anchor strips or rails 15 to opposite sides of the plate adjacent opposite ends thereof. The ends of the rails are fixedly secured to the plate in any suitable manner, while the major portion of the same is spaced therefrom to enable the material from which the body is made to fill the space and provide a firm bond therebetween.

In Figure 2 of the drawing, I have shown several of my ray-proof blocks laid end to end in wall forming arrangement, wherein the end flanges 13 at the adjacent meeting ends of the blocks overlap to seal the joint therebetween as well as to space the blocks one from another. To enable the blocks to be properly aligned, the flanges 13 may be bent angnlarly when being set in position, after which the joint is filled with the usual mortar 16 and the flanges concealed from view. The same arrangement exists between the overlapping flanges 14 when the blocks are positioned one upon the other in tiers and a repetition of the description is not believed necessary. The flanges 13 and 14 of adjacent blocks thus aiford a flat-surfacecontacting non-positive bond between the blocks.

From the foregoing description, it will be seen that when thebloeks 10 are in wall forming position, they present an ordinary appearance, but by reason of the lead plates 12 and the overlappin edges of the same, the

' throughout and is capable of interrupting the path of the rays which revents the same from g therethroug from one side to the ot er.

In Fi re 5 of the drawin I have shown a slight y modified form 0 my invention wherein the anchor rails 15 are stamped out of the lead plate 12' to extend onto opposite sides thereof, the same being flattened so that the sides of the rail overlap each other, and also overlap the side walls of the slot 17 formed in the plate by the stamping of the rails therefrom. This is to prevent the rays which travel in a straight path from possibly passing through any unprotected space. The rails 15' act in the same manner to anchor the plate in the block as do the rails 15 in the preferred, form and the other features thereof are similar so that further explanation is not deemed necessary.

WhileI have described .what I deem to be the most desirable embodiment of my inven tion, it is obvious that many of the details may be varied Without in any way departing from the spirit of my invention, and I there fore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

What is claimed as new is:

1. In a ray-proof built u wall structure, a plurality of X-ray proof locks, each block includin a body, and a lead plate embedded in said 0d and having normally plane ed es 'exten ing beyond the faces of said bo y to provide integral flanges, the flanges of adjacent blocks being bendable and overlapping each other in rigid contacting surface bonding engagement at the joints therebetween during their emplacement, whereb said wall includes a continuous, nonierce sound deadening lining opaque to -rays. 2. In a ray-proof wall structure a plurality of ray-proof blocks, each block including a body, and a lead plate embedded in said body and having a p urality of integral flanges so as to dispose said blocks in proper spaced alignment to produce a continuous nonpierced sound deadening lining opaque to X- rays, said plate including anchor members at opposite sides for securely anchoring said p ate in said inner and outer body members.

In a ray-proof wall structure a plurality of ray-proof blocks, each block includin a bod having inner and outer members, an a lea plate embedded in said body and having a (plurality of integral flanges extending beyon faces of said body members, the flanges of adjacent blocks overlapping each other at joints between said blocks, said flan s being bent angularly into ri id flatsur ace-contactin non-positive bon ing relation as the bloc are set in place so as to dispose said blocks in proper spaced alignment to produce a continuous nonierced sound deadening lining opaque to -rays, said plate including anchor members at opposite sides for securely anchoring said p ate in said body, each of said anchor members being stamped from the body of said lead plate and being flattened to overlap adjacent portions of said plate.

. In testimony whereof I have aflixed my signature.

. DAVID H. BARRY.

flanges of adjacent blocks overlapping each other at joints between said blocks, said flanges being bent angularly into rigid flatsurface-contacting bonding relation as the blocks are set in place so as to disposed said blocks in proper spaced alignment to produce a continuous non-pierced sound deadening lining opaque to X-rays.

3. In a ray-proof wall structure a plurality of ray-proof blocks, each block including inner and outer body members, and a lead plate embedded between said body members, said plate having integral flanges extending beyond upper and side faces of said body members, the flanges of adjacent blocks overlapping each other at joints between said blocks, said flanges being bent angularly into rigid flat-surface-contacting non-positive bonding relation as the blocks are set in place
